Or you can just run intake, header and highflow cat and leave the cat-back alone. I was in Taiwan recently talking to one of the shops near my grandparents house and saw that alot of ppl were switching out the bigger mufflers for stock ones. So I asked the shop owner what the deal was and he told me that alot of the street racers there now run the exact set-up that I just mentioned if not less.

I've seen alot of them run on the street and they seem to be doing pretty well. Loud intake and Vtec engagement and the cars still seem decently fast. Lately I've been wondering if the 2.25 is even worth it anymore.
